Patented Dec. 2, 1930 -UNITED STATES PATENT OFFICE FRANK G. BROTZ, OFKOHLER, WISCONSIN, ASSIGNOR T KOHLER COMPANY, 0F KOHLER, WISCONSIN, ACORPORATION OF WISCONSIN POP-UP WASTE Application med August 6, 1926.Serial No. 127,635.

This invention has for its object to provide a waste fitting for sinksand the like, having a pop-up valve operating on the direct liftprinciple. j

An object'of the invention is to accommodate the offset relation betweenthe operating means and the Waste valve so as to insure freedom ofmovement Without loose connections or connections that will work looseor bind or otherwise cause trouble.

Another object is to provide such direct lift pop-up Waste mechanismthat will be adjustable verticall and horizontally to adapt it tovarying imensions. y

With the above and other objects in view the invention consists in thewaste connection as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters ofreference indicate the same parts in different views,

Fig. 1 is a vertical sectional View through a Waste connection,constructed in accordance with this invention; and

Fig. 2 is a transverse sectional view thereof taken on the line 2-2 ofFig. 1.

In these drawings, lOindicates a sink or preferably the dishwasherreceptacle of a dish-washer and sink combination of porcelain enamelledconstruction, having a recess or depression in its bottom forming awaste outlet 11 somewhat larger than usual within which, is clamped awaste coupling 12 having a flaring funnel-shaped open upper endterminating in a feather edge 13 drawn into close fitting contact withthe enamelled surface of the receptacleby a clamping nut 14 threaded onthe coupling and engaging the bottom of the receptacle with a gaskettherebetween. To the reduced neck of this coupling 12 is threaded awaste housing 15 with- 1n which slidably fits a waste plug 16 serving toseal the outlet when in its lower position as shown, but Acapable ofbeing raised to permit the discharo'e of water through its ports 17 whenraised 1n a manner well known with op-up waste valves. The housing 15has an inclined lateral extension carryino` at'its end a verticalguideway in which a plunger rod 18 fits to havevertical movement, saidrod 50 having a working fit in the guide both above tion andconsequently a special strainer has and below the lateral extension ofthe housing as well as in its passage therethrough and being protectedby a packing gland 19 where it passes out of the upper end of the guide.An inclined connecting rod 2O passes 55 through the lateral extension ofthe housing and connects the waste plug 16 with the plunger rod 18, sothat vertical movements of the latter will be imparted to the former.The lower end of this connecting rod projects through an opening in theWaste plug and its upper end passes through an opening in the plungerrod where it is clamped by a set screw- 21 threaded in the lower end ofthe plunger rod. This set screw is accessible by removing a screwplug\22 which closes the lower end of the guide. When desired means maybe provided for engaging the plunger rod to hold it in its raisedposition, such means as shown consisting of a spring pressed ball detentcontained in a screw plug 23, which is threaded in the wall of theguide, the ball detent thereof being adapted to engage in a recess 24 inthe end of the connecting rod 20.

Slidably fitting in an opening in the projecting upper end of theplunger rod 18 is an arm 25 which is held in its adjustment by a setscrew 26 threaded in the end of the plunger rod, and threaded throughthe other end of the arm 25 is a vertical adjusting rod 27 held in itsadjustment by a set screw 28 inthe end of said arm. A connecting rod 29is pivotally connected with the adjusting rod 27 and With the crank arm30 of a crank handle 31, so that the turning of the handle 3l producesthe necessary vertical movements of the waste plug foropening or closingthe outlet.

In utilizinga sink or the like container for the purpose of washingdishes, or for cleaning and preparing vegetables, there is likely to'beconsiderable waste mutter liable to stop up the strainer 0f ordinaryconstrucbeen designed for this,purpose,.particularly to permit of thecleaning of the strainer by making it removable in the form of a basketor container for the refuse matter which may be easily lifted out andcarried to a garbage receptacle or other place of deposit. Such straineris shown in the drawing as a basketlike strainer 32 with an upwardlyprojecting handle 33 by which it may be carried, there being upwardlyextending flaring edges to the strainer tightly fitting against thefiaring surfaces of the coupling 12. Beneath this strainer is preferablya stationary strainer 34, desirably consisting of a perforated diskresting on an internal fiange 35 and also having a handle by means ofwhich it ma be Vremoved when desired. The position o the stationarystrainer 34 is sufiiciently above the waste plug 16 to permit of thevertical movements of the latter without interference.

By means of this invention, the sink eutlet lnay be closed to cause itto retain water for dish washing, vegetable washing or other purposesand when the pop-up valve is open by the turning of the handletheenlarged strainer surface will permit of the quick discharge,notwithstanding the presence of refuse matter, such matter collecting inthe removable basket-like strainer 32 which may readily be removed andcleaned and when replaced will tightly fit as a plug in its conical 35from the sink either before or after opening the pop-up waste valve. Ifthere are both heavy solids and fioating solids present it is preferableto remove the heavy solids first and then replace the strainer basket tocollect the Heating solids as the water is drained from the containerwhen the valve is opened. In this operation any heavy solids which mayhave settled into the waste pocket while the strainer basket was removedwill be held by the strainer disk 34 and may be removed later.

The construction of the valve operating mechanism is such that there isno possibility of the waste water finding cavities in which to lodge andbecome foul and there is ne chance for it to escape, but the offsetplunger rod parallel with the waste plug and coupled therewith affords atightly packed medium for connection between the waste plug and f itslifting mechanism. The detent serves to hold the valve in its openposition though this may be effected by the usual offset in theconnecting rod 29 permitting the crank handle 31 to pass over deadcenter. The adjustments of the adjusting rod 27 in the arm 25 and theadjustments of the arm 25 in the e plunger rod\18 permit of compensationbeing made for variations in either vertical or horipop-up waste'without parts likely to become loose to rcquire repair.

IVhat I claim as new and desire to secure by Letters Patent is 1. Apop-np waste valve comprising a housing forming spaced vertical guideswith a narrow inclined connection between them, a waste plug having atubular stem fitting in one guide of the housing and a plunger rodfitting in the other guide of the housing, a connecting rod secured tethe plunger rod and engaging in an opening of the stem of the wasteplug, a valve seat for the waste plug connected with the housing, andmeans for lifting the plunger rod to lift the waste plug, the stem ofsaid waste plug being of sufficient length to avoid uncovering theconnection between the guides in the open position of the waste plug.

2. A pop-up waste valve comprising a housing forming a pair of' verticalguides spaced apart with an inclined connection between them, a wasteplugv having a tubular stem fitting in one of the guides and extendingbeyond the connection, a valve seat for the waste plug connected withthe housing, a plunger rod mounted in the other guide, a connecting rodconnecting the plunger rod with the stem of the waste plug and passingthrough the connection, and means for lifting the plunger rod to liftthe waste plug, the tubular stem of said waste plug extending beyond theconnection a greater distance than the travel of the waste plug, wherebysaid connection is not uncovered thereby.

3. A pop-up waste valve comprising a housing forming spaced verticalguides with an inclined connection between them, a waste plug fitting inone guide, a plunger rod fitting in the other guide, a connectin rodpassing, through the connection and fitting in an opening in the plungerrod, a set screw in the lower end of the plungerrod for engaging theconnection, a screw plug fitting in the lower end of the guide for theplunger rod, said connecting rod passing through an opening in thetubular stem of the waste plg, and means for operating the plunger ro 4.In a pop-up waste valve, a housing forming spaced vertical guides with aconnection between them, a waste plug fitting in one guide, a plungerrod tting in the other guide, a connecting rod passing through theconnection and engaged with the waste plug and plunger rod, means foroperating the plunger rod, and a spring detent engaging the plunger rodfor holding it in its raised' position.

In testimony whereof, I affix my signature.
